So... I'm at the gym and this cute female I've seen often walks past me on the way to a leg machine. As she does this, she looks me right in the eye and smile. I was a bit caught off guard by it as I had just finished a set on the leg curls, but I smiled back. She then hops on the machine next to me and does a few sets before walking off. The entire time I'm thinking, "should I make an approach while she's resting"? I didn't approach at all...

What do you guys think? Should I talk to her the next time I see her, or would it just be awkward as she might think I pussed out last time?... I kind of disobeyed the 3 second rule.
